identification and the proper use of tools and shop equipment.

2. Retrieve vehicle service information.3. Identify the strength ratings of threaded fasteners.4. Describe how to safely hoist a vehicle.5. Discuss how to safely use hand tools.6. Identify the personal protective equipment (PPE) that all

service technicians should wear.7. Describe what tool is the best to use for each job.8. Explain the difference between the brand name (trade

name) and the proper name for tools.9. Explain how to maintain hand tools.10. Identify the precautions that should be followed when

working on hybrid electric vehicles.

VEHICLE IDENTIFICATIONMAKE, MODEL, AND YEAR

• All service work requires that the vehicle and its components be properly identified.

• The most common identification is the make, model, and year of the vehicle.• Make: e.g., Chevrolet• Model: e.g., Impala• Year: e.g., 2008



VEHICLE IDENTIFICATIONVEHICLE IDENTIFICATION NUMBER

• The year of the vehicle is often difficult to determine exactly.

• A model may be introduced as the next year’s model as soon as January of the previous year.

• Typically, a new model year starts in September or October of the year prior to the actual new year, but not always.

• This is why the vehicle identification number, usually abbreviated VIN, is so important.




FIGURE 1-1 Typical vehicle identification number (VIN) as viewed through the windshield.




The first number or letter in the VIN identifies the country where the vehicle

was made.




The pattern repeats every 30 years for the year of manufacture.



VEHICLE IDENTIFICATIONVEHICLE SAFETY CERTIFICATION LABEL

• A vehicle safety certification label is attached to the left side pillar post on the rearward-facing section of the left front door.

• This label indicates the month and year of manufacture as well as the gross vehicle weight rating (GVWR), the gross axle weight rating (GAWR), and the vehicle identification number (VIN).



VEHICLE IDENTIFICATIONVECI LABEL

• The vehicle emissions control information (VECI) label under the hood of the vehicle shows informative settings and emission hose routing information.

FIGURE 1-2 The vehicle emission control information (VECI) sticker is placed under the hood.



VEHICLE IDENTIFICATIONCALIBRATION CODES

• Calibration codes are usually located on Powertrain Control Modules (PCMs) or other controllers.

• Whenever diagnosing an engine operating fault, it is often necessary to use the calibration code to be sure that the vehicle is the subject of a technical service bulletin or other service procedure.

FIGURE 1-3 A typical calibration code sticker on the case of a controller. The information on this sticker is often needed when ordering parts or a replacement controller.



VEHICLE IDENTIFICATIONCASTING NUMBERS

• When an engine part such as a block is cast, a number is put into the mold to identify the casting.

• These casting numbers can be used to identify the part and check dimensions such as the cubic inch displacement and other information, such as the year of manufacture. FIGURE 1–4 Casting numbers on major

components can be either cast or stamped.



SERVICE INFORMATIONSERVICE MANUALS

• Service information is used by the service technician to determine specifications and service procedures, and any needed special tools.

• Factory and aftermarket service manuals contain specifications and service procedures.

• While factory service manuals cover just one year and one or more models of the same vehicle, most aftermarket service manufacturers cover multiple years and/or models in one manual.



SERVICE INFORMATIONSERVICE MANUALS

• Included in most service manuals are the following:• Capacities and recommended specifications for all

fluids• Specifications including engine and routine

maintenance items• Testing procedures• Service procedures including the use of special

tools when needed



SERVICE INFORMATIONELECTRONIC SERVICE INFORMATION

• Electronic service information is available mostly by subscription and provides access to an Internet site where service manual-type information is available.

FIGURE 1–5 Electronic service information is available from aftermarket sources such as All-Data and Mitchellon-Demand, as well as on websites hosted by vehicle manufacturers.



SERVICE INFORMATIONTECHNICAL SERVICE BULLETINS

• Technical service bulletins, often abbreviated TSB, sometimes called technical service information bulletins (TSIB) are issued by the vehicle manufacturer to notify service technicians of a problem and include the necessary corrective action.

• Technical service bulletins are designed for dealership technicians but are republished by aftermarket companies and made available along with other service information to shops and vehicle repair facilities.

FIGURE 1–6 Technical service bulletins (TSB) are issued by vehicle manufacturers when a fault occurs that affects many vehicles with the same problem. The TSB then provides the fix for the problem including any parts needed and detailed instructions.



SERVICE INFORMATIONINTERNET

• The Internet has opened the field for information exchange and access to technical advice.

• One of the most useful websites is the International Automotive Technician’s Network at www.iatn.net.

• This is a free site but service technicians must register to join.

• If a small monthly sponsor fee is paid, the shop or service technician can gain access to the archives, which include thousands of successful repairs in the searchable database.



SERVICE INFORMATIONRECALLS AND CAMPAIGNS

• A recall or campaign is issued by a vehicle manufacturer and a notice is sent to all owners in the event of a safety-related fault or concern.

• While these faults may be repaired by shops, it is generally handled by a local dealer.

• Items that have created recalls in the past have included potential fuel system leakage problems, exhaust leakage, or electrical malfunctions that could cause a possible fire or the engine to stall.

• Unlike technical service bulletins whose cost is only covered when the vehicle is within the warranty period, a recall or campaign is always done at no cost to the vehicle owner.



What Should Be Included on a Work Order?

• A work order is a legal document that should include the following information:1. Customer information2. Identification of the vehicle including the VIN3. Related service history information4. The “three Cs”:

• Customer concern (complaint)• Cause of the concern• Correction or repairs that were required to

return the vehicle to proper operation.
